Search Worlds Without End

In a universe protected by the Three Laws of Robotics, human are safe.

The First Law states: A robot may not injure a human being, or, through inaction, allow a human being to come to harm.

When an experiment with a new type of robot brain goes awry, the unthinkable happens.
Caliban is created...

A robot without guilt or conscience, a robot with no knowledge of or compassion for humanity... a robot without the Three Laws.

Isaac Asimov's famous Three Laws provide far-future humanity with omni-compliant robots, but ultimately lead to the hell of existence with all challenges removed. Thus Asimov proposed the New Laws to Roger MacBride Allen, laws which endow helping hands, not slaves.

But the upheaval this creates, on planets where humans are split into two antagonistic cultures and the idea of working alongside free-thinking mechanicals produces terrible anxiety, is enormous... On the decaying world of Inferno, the no-law robot Caliban finds himself intermediary in the complex relations between robots and humans. But when a key politician is murdered, fear of Caliban as the robot without guilt or conscience, the one who could start the rebellion to overthrow all humanity escalates - and crisis begins.

On Inferno the tensions between Spacer and Settler are as strong as ever, but now the majority of robots are working on terraforming rather than as personal servants. Governor Alvar Kresh is content to have his wife give support to the renegade robot leaders she has created, but is not so keen to advertise the fact. Caliban and Prospero, New Law robots, and their fellows have settled in Valhalla, a city in the northern Utopia region. What they are unaware of is that in order to bring the climatic changes essential for further terraforming, the Governora and his political colleagues are planning to bring down the Comet Grieg on Utopia causing massive devastation and creating an artificial sea.
